Application filed Hatch 7, 1917. Serial No. 158,059.

To all whom it. may concern:

Be it known that I, ORA STALEY, a c1tizen of the United States, residing at Ind1anapo lis, in the county of Marion and State of tween the-cooperating compression members.

It is within the province of thedisclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combina- .tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the sccpe of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:-

Figure 1 is a side elevation, parts being broken away;

Fig. 2' is a top plan;

Fig. 3 is a section showing a. modified clamping lever; and

Fig. 4 is an elevation of the modified lever.

The device forming the subject matter of this application preferably is made of metal throughout and includes a base 1 provided at one extremity with an upturned end 2, and broadened at the other extremity to form a foot 3. The numeral 4 denotes an arm, one extremity of which is united by a pivot element 5 with the end 2 of the base 1. The other end of the arm 4 terminates The bottom 17 of the-pan The numeral 9 denotes a. bifurcated lever including a head 10 and arms 11 the head 10 having a finger piece 12 whereby the lever may be swung, the lever straddling the arm 4 and the base 1 the lower ends of the arms 11 being united by means of a pivot element 14 with the base 1. The arm 4 is provided on its upper side and above and to the front of the pivot element 5, with a cam edge 15 wherewith the head 10 of the lever coacts, so as to press the compremion members 8 and 4 on the patch and on the article to be vulcanized.

The tube or other article to be patched is denoted by the numeral 16 and rests on the foot 3. A patch 21 of vulcanizable material is placed on the tube 16. Under the concaved bottom 17 of the pan 8 is placed a layer of absorbent material 19, which may be blotting paper, if desired, although some other substance may be used, the absorbent member 19, whatever be its construction, being moistened preferably with water. Superposed on the bottom 17 of the pan is a mass of fuel 20. Any kind of fuel maybe used, either liquid or solid. I prefer, how ever, to use a solid fuel, and in this connection, a piece of cardboard saturated in a solution of saltpeter may be found useful.

In practical operation, by swinging the lever 9 up into a substantially vertical position, the tube 16 or other article to be patched, and the patch 21 may be put in place and may then be clamped tightly between the pan 8 and the foot. The fuel is ignited, and the absorbent member 19 is heated, the liquid therein contained being converted into steam, which moderates the heat from the pan. The absorbent member 19, being carried in the concavity 18 in the bottom 17 of the pan, is in direct contact with the patch 21, the patch being vulcanized to the tube 16 by steam moderated heat. In this way, an even heat is secured,

an excessive heating is not likely, and a the arm 4 for the purpose of holding the lever in place against swinging movement, and to aid in applying pressure to the pan.

Having thus described the invention, what is claimed is 1. A vulcanizer comprising upper and lower compression members, the upper member being cup-shaped to retain fuel; and an absorbent element in direct contact with the lower face of the upper compression member.

2. A vulcanizer comprising first and second cooperating compression members, the first compression member bein provided with fuel-holding means upon its exposed side,'and with a cavity on its working side; and an absorbent element completely housed in the cavity, the second compression member being of sufficient size to press the material to be vulcanized against the peri hery of the first compression member there y to render the cavity air-tight.

3, A vulcanizer comprising a base and an arm pivoted to the base, the arm and the base being provided with cooperating compression members; and a lever pivoted to the base for swinging movement longitudinally of the arm, the arm being provided with a longitudinally convexed cam edge wherewith a portion of the lever coacts when the lever is swung, to secure a cooperation between the compression members.

4. A vulcanizer comprising a base and an arm pivoted to the base, the base and the arm being supplied with cooperating compression members, and the'arm being provided with a convexed cam edge; a forked lever straddled on the arm and the base and having its extremities pivoted to the base, the lever including a head; and a movable holding device carried by the head and coacting with the cam edge to press the compression members togethenthe holdingdevice constituting a means whereby the lever may be prevented from swinging with respect to the arm. a

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

ORA STALEY. Witnesses:
